Claims21
A drive mechanism for use with an implement comprising a driving sprocket to drive a rotatable workpiece and at least one intermediate sprocket of different diameter to the driving sprocket to allow for change of speed and torque of the rotatable workpiece.
A method of varying the speed and torque of a rotatable workpiece, comprising the steps of using a drive mechanism for use with a hand-operated implement for cutting materials comprising a driving sprocket to drive a rotatable workpiece and at least one intermediate sprocket of different diameter to the driving sprocket to allow for variation of speed and torque of the rotatable workpiece.
A drive train for use with an implement comprising a driving sprocket to drive a rotatable wheel or component, with at least one intermediate, stepped sprocket of different diameter to the driving sprocket to change the speed and torque of the rotatable wheel or component, wherein the or each intermediate sprocket is mounted for free longitudinal movement within a hollow shaft to allow for two or more chains to be tighten equally and together at one end.
